To combat this, many antimalware programs monitor program behaviors, often called heuristics, to catch previously unrecognized malware. Other programs use virtualized environments, system monitoring, network traffic detection and all of the above to be more accurate. Still they fail us on a regular basis. If they fail, you need to know how to spot malware that got through.
Antimalware software provides little peace of mind in today’s danger landscape. Antimalware scanners are notoriously wrong, especially when it comes to exploits that are less than 24 hours old. Hackers and software that are malicious can change their strategies at any time. By changing a few bytes, a previously identified malicious programme becomes unrecognisable. Simply upload any suspected malware file to Google’s VirusTotal, which includes over 60 different antimalware scanners, to discover that detection rates aren’t always as high as stated.
